Merge branch 'ipa-next' 

Alex Elder says:

====================
net: ipa: support two more platforms

This series adds IPA support for two more Qualcomm SoCs.

The first patch updates the DT binding to add compatible strings.

The second temporarily disables checksum offload support for IPA
version 4.5 and above.  Changes are required to the RMNet driver
to support the "inline" checksum offload used for IPA v4.5+, and
once those are present this capability will be enabled for IPA.

The third and fourth patches add configuration data for IPA versions
4.5 (used for the SDX55 SoC) and 4.11 (used for the SD7280 SoC).
